    摘要: A method and apparatus for setting the amount of exposure for the photodetector array in a barcode scanner. An image is captured with the photodetector array. The type for each sub-region in the multiple sub-regions in the image captured is determined. Each sub-region in the multiple sub-regions is assigned a weight based on the type of the sub-region. The amount of exposure for the photodetector array in the barcode scanner is set automatically based on the weight for each sub-region in the multiple sub-regions. In some embodiments, the predetermined image area are repartitioned into new multiple sub-regions based on the image captured, and the amount of exposure for the photodetector array in the barcode scanner is set automatically based on the weight for each sub-region in the new multiple sub-regions.

    摘要: An aiming assembly supported by a mobile imaging reader projects a visual prompt, preferably one or more arrows, on a symbol to indicate a direction in which a field of view of an imager in the housing is to be moved in order to position the symbol entirely within the field of view prior to electro-optically reading the symbol.

    摘要: An arrangement for, and a method of, preventing a misread of a one-dimensional symbol that can be read in either one of two polarities in an electro-optical reader. A data capture assembly captures light from the symbol, and generates an electrical signal indicative of the captured light. A controller simultaneously processes and decodes the electrical signal as a first decoded result of one of the polarities and as a second decoded result of the other of the polarities. The controller also determines the validity of the first and second decoded results, and generates an output in dependence upon the validity determination.
